Definitions

  • the invention relates to actuators which are known in various embodiments from the prior art and practice.
  • Actuators comprise an actuator housing in which an actuator motor is arranged and are used, for example, to operate fittings and / or valves.
  • the object of the invention is to create an actuator of the type mentioned at the outset, which can be easily installed even in a comparatively small space.
  • an actuator with the features of the first independent claim directed to such an actuator is created.
  • an actuator with an actuator housing is proposed in which an actuator motor is arranged, the actuator housing having at least one step with at least one functional surface on which at least one access to the actuator housing can be and / or is formed.
  • the step on the housing creates a functional surface that can be arranged, for example, on a freely accessible front or rear of the actuator housing.
  • the functional surface can be used to attach position indicators, for electrical connections in the Housing and / or, for example, can also be used to insert an end stop screw which limits the travel of the drive and / or of a valve or a fitting operated by the actuator.
  • the actuator according to the invention can be placed in the installation space provided for it in such a way that lateral surfaces of the actuator housing do not have to be accessible. In this way it is possible, for example, to arrange several actuators of this type close to one another in order to make the best possible use of the available installation space.
  • the actuator housing can comprise at least two housing parts which are arranged offset from one another to form the step.
  • the at least two housing parts can be arranged offset from one another, for example, transversely to an axis of rotation of the actuator motor.
  • the offset of the at least two housing parts to one another can be the cause of the formation of the step and thus the cause of the formation of the functional surface.
  • the at least one functional surface formed on the step and / or caused by the offset can be oriented at right angles to a direction of the offset.
  • a vector that can be used to describe the direction of the offset is at right angles to the functional surface.
  • At least one functional surface of the actuator caused by the offset is aligned in the direction of the offset.
  • a vector, with which the direction of the offset can be described can lie approximately or partially within the functional area.
  • an actuator which has the means and features of the second independent claim directed to such a claim.
  • an actuator is thus proposed which has a handwheel which is arranged, preferably eccentrically, on one, for example one of the at least one previously mentioned functional surface, one, for example, on the previously mentioned actuator housing.
  • the handwheel has a diameter that is at most as large, preferably smaller than, a largest measurable distance between two opposing outer sides, between which a center of rotation of the handwheel is arranged.
  • the handwheel can in particular protrude laterally beyond one of the aforementioned outer sides of the actuator housing of the actuator. In this way, it is possible to position several such actuators close to one another, since in this embodiment of an actuator too, lateral housing surfaces can remain free of functional elements, for example free of a handwheel. An actuator is thus created which is particularly suitable for integration in a comparatively small installation space.
  • the handwheel can be arranged, for example, on one side, in particular on an end face, of a step, for example the one already mentioned above, of the actuator housing.
  • the actuator motor can be arranged in one of at least two housing parts of the actuator housing.
  • An actuator output shaft can be arranged on a housing part of the actuator housing offset therefrom.
  • the actuator motor can be connected to the actuator output shaft via an actuator gear. It can be Actuator gears extend from the housing part with the actuator motor into the housing part with the actuator output shaft. The actuating drive gear thus allows the actuating drive motor to be spatially spaced apart from one another in one housing part from the actuating drive output shaft which is arranged in the other housing part.
  • At least one functional surface of the at least one previously mentioned functional surface is formed between an upper side and an underside of the actuator housing.
  • a functional surface of the at least one functional surface can be formed on a side of the actuator housing that faces away from an upper side of the actuator housing.
  • a bushing for an electrical connection in the actuator housing can be formed on this functional surface.
  • a functional surface of the at least one functional surface is formed on a side of the actuator housing that faces away from an underside of the actuator housing. In one embodiment of the actuator, a functional surface of the at least one functional surface can be arranged on a side of the housing that faces away from a side from which one, for example the previously mentioned, actuator output shaft emerges.
  • a functional surface of the at least one functional surface can be in an axial extension of the actuator output shaft and preferably with at least one display and / or at least an end stop screw and / or at least one operating element.
  • the previously mentioned end stop screw can also be referred to as the end position adjusting screw.
  • the actuator housing can also have a functional surface in an axial extension of the actuator motor.
  • the object of a further aspect of the invention is therefore to create an actuator, in particular one as already described above, which can be controlled by means of Bluetooth and at the same time has explosion protection that is comparatively easy to implement.
  • an actuator with the features of the third independent claim directed to such an actuator is proposed.
  • an actuator is proposed to achieve the object, which has an actuator housing with at least one communication hole as a passage opening for a Bluetooth signal from the actuator housing, the communication hole having a maximum diameter of 30 mm and is closed with a viewing window, and wherein an LED is arranged in the actuator housing, the LED signal of which is perceptible through the viewing window for a user of the actuator.
  • the communication hole can have a maximum diameter of 25 mm.
  • a communication hole with a maximum diameter of 30 mm, preferably a maximum of 25 mm is sufficiently large for Bluetooth signals to be able to pass the communication hole to a satisfactory extent.
  • the communication hole as a passage opening for Bluetooth signals is comparatively small, so that a display, as it is already known from practice, may be difficult or difficult to integrate, this is compensated for by the use of at least one LED for status display.
  • the actuator according to the invention is distinguished by an explosion protection that is easier to implement.
  • the comparatively small communication hole can be closed with a correspondingly small window in order to meet the explosion protection requirements that are often required.
  • the material and ultimately also the cost of providing the desired explosion protection with the actuator according to the invention is lower than with such actuators that have comparatively large displays, without the functionality offered by the actuator being impaired.
  • a Bluetooth module is provided behind the window in the actuator housing. In this way is a low-interference or even Interference-free communication with the Bluetooth module is possible, even if the actuator housing itself is made of a material that shields radio signals.
  • the Bluetooth module is arranged in a central spot of a projection of the communication hole onto a circuit board with the Bluetooth module. In this way it is ensured that the Bluetooth module is arranged as possible in the center of the communication hole, so that Bluetooth signals that are to be exchanged between the Bluetooth module and a receiver and / or transmitter from as many directions as possible reliably reach the Bluetooth module reachable. This measure enables the transmission and reception range of the Bluetooth module located within the actuator housing to be maximized.
  • the Bluetooth module can, for example, be at a distance between 0 mm and 15 mm, particularly preferably at a distance between 5 mm and 10 mm, to the aforementioned central spot and / or to the communication hole and / or to the viewing window with which the communication hole is closed, be arranged.
  • an LED as a status display means of the actuator makes it possible, in one embodiment of the actuator, to display this outside the aforementioned central spot of the projection of the communication hole onto the circuit board to be arranged with the Bluetooth module. In this way, the installation space available in the area of the central spot can be used for the Bluetooth module and / or an antenna of the Bluetooth module. A light signal emitted by the LED can still be perceived by a user through the communication hole when the LED is arranged outside the aforementioned central spot.
  • the viewing window with which the communication hole is closed is made of a diffuse material.
  • the light signal emitted by the LED inside the actuator housing can be scattered through the diffuse material of the viewing window. So it can be seen from the outside largely independent of the position of the LED inside the actuator housing.
  • the Bluetooth module is arranged in SMD technology on a printed circuit board, for example the one already mentioned above. Furthermore, an integrated antenna of the Bluetooth module can be arranged in a, for example the already mentioned, central spot of a projection of the communication hole onto a, for example the already mentioned, printed circuit board with the Bluetooth module. The transmission range and the reception range of the Bluetooth module can be optimized by an antenna of the Bluetooth module arranged in the central spot.
  • a distance of the Bluetooth module from the communication hole can be smaller than an axial length of the communication hole. This measure can also help to compensate for the comparatively small size of the communication hole and the shielding effect of the actuator housing and thereby simplifying communication with the bluetooth module behind the communication hole.
  • the actuator has a control device which is set up to read out and process status messages from the actuator.
  • the control device can also be set up to control the LED in accordance with the status messages for outputting status information.
  • status information of the actuator can be output via the LED.
  • the use of a comparatively large display for displaying the status is therefore unnecessary. This is advantageous against the background of the desired compactness and the explosion protection of the actuator, which is as easy to implement as possible, since a display on the one hand requires more installation space and therefore a larger actuator housing and on the other hand a correspondingly large housing opening in the actuator housing, which the explosion protection measures that are then provided on the actuator housing have to make it difficult.
  • the object of the invention is to provide a space-saving concept for screw locking such end stop screws in actuators and thus to create an actuator which can be easily integrated even in a small installation space.
  • an actuator with the features of the further independent claim directed to such an actuator is proposed.
  • an actuator with an actuator housing with at least one adjustable end stop screw as an end stop for an adjusting movement of the actuator is proposed to solve the problem, the end stop screw being positively secured with a screw lock in the form of a locking sleeve.
  • the locking sleeve is arranged in the locking position between an outer circumference of a screw head of the end stop screw and an inner circumferential wall of a screw hole of the actuator housing into which the end stop screw is screwed, preferably under pressure.
  • the locking sleeve is thus squeezed between the outer circumference of the screw head of the end stop screw and the inner circumferential wall of the screw hole for the end stop screw, for example when tightening the end stop screw, and can thus prevent the end stop screw from moving as a result of movements, impacts and / or vibrations that affect the actuator can, unintentionally releases, whereby the end stop for the actuating movement of the actuator could be adjusted.
  • a tolerance ring and / or a tolerance sleeve can be used as the securing sleeve, as are known, for example, as frictional and detachable connecting elements in shaft-hub connections.
  • Such a tolerance ring and / or such a tolerance sleeve can be produced, for example, from a slotted ring made of spring band material with wave-like characteristics.
  • a tolerance ring and / or a tolerance sleeve in particular a shaft-hub connection, is proposed as a screw locking device for an end stop screw of an actuator, in particular an actuator according to one of the claims directed to an actuator.
  • the actuator 1 has an actuator housing 2 in which an actuator motor 3 is arranged.
  • the actuator housing 2 has at least one step 4 on which a functional surface 5 is formed.
  • a total of two accesses 6 and 7 are formed into the actuator housing 2 on the functional surface 5.
  • the actuator housing 2 of the actuator 1 comprises three housing parts 8, 9, 10, the two outer housing parts 8 and 10 being offset from one another transversely to a rotation axis of the actuator motor 3 to form the step 4 of the actuator housing 2.
  • the offset between the two housing parts 8 and 10 can be seen as the cause of the formation of the step 4 on the one hand and the functional surface 5 on the other hand.
  • the functional surface 5 is formed on the middle housing part 9 of the actuator housing 2 and is aligned transversely to a direction of the offset of the two other housing parts 8 and 10 with respect to one another.
  • offset of the two housing parts 8 and 10 with respect to one another means that the longitudinal center axes of the building parts 8 and 10 are not congruent but are arranged offset from one another.
  • the actuator 1 also has a handwheel 11 with which the actuator 1 can be operated manually if necessary.
  • the handwheel 11 is arranged eccentrically on a further functional surface 12 formed on the lower housing part 10 of the actuator housing 2.

  • Figure 4 shows that the handwheel 11 protrudes laterally beyond the right outer side 14 of the actuator housing 2 and is arranged on an end face or front side of the lower housing part 10.
  • the actuator motor 3 of the actuator 1 is arranged in the upper housing part 8 and the middle housing part 9 of the actuator housing 2, an actuator output shaft 15 being arranged on the lower housing part 10 offset thereto.
  • the actuator motor 3 is connected to the actuator output shaft 15 via an actuator gear 16.
  • the actuator gear 16 extends at least partially within the middle housing part 9 of the actuator housing 2 and thus connects the actuator 3 in the upper housing part 8 with the actuator output shaft 15 in / on the lower housing part 10.

  • This further functional surface 19 is located on a lower rear side of the middle housing part 9, that is to say it faces away from the step 4.
  • This further functional surface 19 on the middle housing part 9 of the actuator housing 2 is ultimately only created in that the upper housing part 8 is arranged offset from the lower housing part 10 on the middle housing part 9 of the actuator housing 2.
  • the functional surface 5 on the step 4 of the actuator housing 2 and the further functional surface 19 face away from one another.
